Not to be an unskewer but this poll has a few minor issues.
1. Its last iteration was a C +14 outlier.
2. It under samples whites 67% to a likely 70%.
3. It also under samples Non-College degree whites at about 51-52% of the white vote vs 55% in 2012. If anything I would think the NCD white vote proportion will be a higher this year, maybe as high as 58-60% (its at least 67% in the general population).
I agree the last one was an outlier, but C+7 seems to fit in with what other reputable polls are putting out. 15 to 7 is a massive correction.
